含齿廓偏差的斜齿轮动力学特性研究

Study on the Dynamics Characteristic of Helical Gear with Tooth Profile Deviation

为了研究齿廓偏差对斜齿轮动力学特性的影响,基于理论渐开线和齿廓总偏差值建立了含齿廓偏差的误差渐开线数学模型,并以一对渐开线斜齿轮为研究对象,利用UG建立了含齿廓偏差的斜齿轮副三维模型,运用ADAMS对理想模型的可靠性进行验证,同时结合ANSYS对理想和误差模型的从动轮角速度、从动轮角加速度进行了对比分析。结果表明,ADMAS动力学仿真与ANSYS瞬态动力学分析得到的结论基本吻合,即齿廓偏差的存在对斜齿轮副从动轮角速度、从动轮角加速度影响显著。

For study the impact of the tooth profile total deviation on the dynamics characteristic of helical gear,based on theoretical involute and tooth profile total deviation value,the mathematical model of error involute with tooth profile deviation is established.By taking a involute helical gear pair as the research object,the 3D model of helical gear pair with tooth profile deviation is established by using UG,and the reliability of the ideal model is verified by using ADAMS.Meanwhile,combining the ANSYS,the angular velocity,angular acceleration of driven gear of the error model and ideal model are compared and analyzed.The results show that the conclusion in dynamics simulation based on ADAMS is the nearly same as transient kinetic analysis based on ANSYS.The tooth profile deviation has significant effect on the angular velocity and angular acceleration of driven gear.
